narrowed in front and narrowed behind, closely punctate, with two small tubercles at the apex, two 
others on each side of the disc in a line with them, and several more at the sides between the middle 
and the apex, the disc with an abbreviated median carina. LElytra ovate, moderately convex, seriate- 
punctate, the interstices 3, 5, and 7 each with a series of very small, smooth, conical tubercles, the others 
with scattered granular prominences, 
Length 44, breadth 2 millim. ( 9.)

One specimen. Very like A. verrucosus, and perhaps an extreme form of it, but 
with the tubercles on the elytra reduced to very small conical prominences, the 
prothorax less uneven above, with some very small tubercles at the sides and along 
either side of the middle of the disc. The rostrum is a little less constricted at the 
base, and similarly tuberculate.

Distinguishable by its convex, obovate form, the very short setosity, the strongly 
constricted rostrum, the anteriorly constricted, very coarsely punctured, transverse 
prothorax, and the regularly seriato-granulate elytral interstices, the granular 
elevations closely placed and extending from the base to the apex, the seriate 
punctures fine, the second interstice with a conspicuous tubercle before the apex. 
We are indebted to the authorities of the Dresden Museum for a specimen of 
this species; it is labelled as having been obtained originally from Motschulsky. 
There is a closely allied undescribed form from Cocos Island in the British Museum. 
45, Anchonus murcidus. (Tab. VI. figg. 15, 15a, ¢.) 
Anchonus murcidus, Faust, Deutsche ent. Zeit. 1892, pp. 27, 46 (¢)’. 
Oblong, convex, black, the antenne and tarsi rufescent; the sete short. Rostrum stout, curved, slightly 
thickened towards the base, and there abruptly constricted, coarsely, closely punctate. Prothorax 
transverse, emarginate at the apex, slightly rounded at the sides, narrowed and constricted in front and 
narrowed behind; the surface coarsely, closely punctate, with the narrow interspaces here and there 
raised and shining. Elytra oblong-ovate, scarcely wider than the prothorax at the base; seriate- 
punctate, the interstices 2-7 (viewed laterally) interruptedly convex, and with scattered, smooth, granular 
elevations. 
Length 54, breadth 24 millim. (¢.)

In its basally constricted rostrum this species approaches dA. panamensis, Faust, 
from which it differs in its more oblong shape, the less constricted prothorax, and 
very dissimilar elytral sculpture. Dr. Heller has been kind enough to compare the 
single specimen received by us with the type in the Dresden Museum.
